Replacement flat-free wheelbarrow wheel. 4.00-6 size. 309 lb load capacity per wheel. Flat-free wheels are designed to absorb shocks and vibrations caused by obstacles or irregular surfaces, and like pneumatic wheels, they help move delicate loads smoothly and safely over uneven or rough surfaces. The advantage of flat-free over pneumatic is that they are puncture-free and resistant to cold, with no pressure loss or flats. Made of durable and light-weight polyurethan micro-cellular foam. Equipped with ball bearing and grease fitting. Centered metal hub. Knobby tread. Axle diameter: 5/8"". Not for highway use.
